Technical processing work is, perhaps, the area in the whole library work where the highest degree of professional expertise is needed. Therefore, the technical department should be manned by persons who have proven abilities and aptitude for technical work. They should be adept at classification and well conversant with the intricacies of the catalogue code. As far as possible, knowledge of different languages and a background in different subjects must be ensured in the selection of personnel. Further, the staff should have a good handwriting if the catalogue cards are to be handwritten. They should be persons who can do things with a high degree of precision. The chief of the Technical Department should be an experienced hand who can exercise effective supervision over his staff and coordinate the work done by several persons while maintaining consistency and accuracy.
The Technical Department must possess all the tools necessary for classification and cataloguing work to be done in the library. Some of the important tools are:
1) Classification schedule(s)
2) Catalogue Code or Subject Headings List
3) Reference Tools - standard dictionaries including language dictionaries, subject dictionaries and bibliographical dictionaries, encyclopaedias; geographical sources; handbooks, etc.
4) Bibliographies - Indian National Bibliography, British National Bibliography, Accession Lists of important libraries, etc
In the case of classification schemes and Catalogue Codes, "how-to-use" manuals are brought out. These may be acquired for ensuring consistency and uniformity in classification and cataloguing work. As individual institutions libraries adopt different practices to suit local requirements, it maybe helpful for preparing their own manuals which may be useful not only for technical processing, but also for training new entrants.
